Chrysanthemum plant named &#39;dreamy yomarilyn&#39;

ABSTRACT

A distinct cultivar of Chrysanthemum plant named ‘Dreamy Yomarilyn’, characterized by its upright plant habit; freely branching growth habit; uniform and freely flowering habit; decorative-type inflorescences; and light yellow ray florets.

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and hereinafter referred to by the name ‘Dreamy Yomarilyn’.

[0002] The new cultivar is a product of a planned breeding program conducted by the Inventor in Salinas, California and Fort Myers, Florida. The objective of the breeding program is to create new garden-type Chrysanthemum cultivars having inflorescences with desirable inflorescence forms, attractive floret colors and good garden performance.

[0003] The new Chrysanthemum is a naturally-occurring whole plant mutation of a proprietary induced mutation that originated by exposing unrooted cuttings ofthe Chrysanthemum cultivar Yomarilyn, disclosed in U.S. Plant Patent application Ser. No. 09/224,724, to X-ray radiation in March, 1997, in Fort Myers, Florida. The new Chrysanthemum was discovered and selected by the Inventor as a single flowering plant within a population of flowering plants of the irradiated selection in October, 1997 in a controlled environment in Salinas, California. The selection of this plant was based on its desirable inflorescence form, attractive ray floret color and good garden performance.

[0004] Asexual reproduction ofthe new cultivar by terminal cuttings taken in a controlled environment in Salinas, Calif. since December, 1997, has shown that the unique features ofthis new Chrysanthemum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

[0005] The cultivar Dreamy Yomarilyn has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

[0006] The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dreamy Yomarilyn’. These characteristics in combination distinguish ‘Dreamy Yomarilyn’ as a new and distinct cultivar: 1. Upright and compact plant habit. 2. Freely branching, dense, full plants. 3. Uniform and freely flowering. 4. Decorative-type inflorescences. 5. Light yellow-colored ray florets.

[0007] Compared to plants of the cultivar Yomarilyn, plants of the new Chrysanthemum flower slightly later and differ in ray floret color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

[0008] The accompanying photographs illustrate the overall appearance of the new Chrysanthemum. These photographs show the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Chrysanthemum. The photograph at the top of the sheet comprises a side perspective view of a typical flowering plant of ‘Dreamy Yomarilyn’. The photograph at the bottom of the sheet comprises a close-up view of typical inflorescences of the cultivar ‘Dreamy Yomarilyn’.

DETAILED BOTANICAL DESCRIPTION

[0009] In the following description, color references are made to the Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used. The following observations and measurements describe plants grown in Salinas, California, under conditions which approximate those generally used in commercial garden Chrysanthemum production. One rooted cutting was planted in a 15-cm container in July, 2000 and plants were grown under natural season conditions. Plants were not pinched, that is, the terminal apex was not removed to enhance branching. Measurements and numerical values represent averages for typical flowering plants.

Mature foliage lower surface: 147B. Venation upper surface: 147B. Venation lower surface: 147B. Petiloe lenght: About 1.4 cm. Petiole diameter: About 3 mm. Petiole color, both surfaces: Close to 146B to 146C.

[0025] INFLORESCENCE DESCRIPTION:

[0026]Appearance.—Decorative-type inflorescence form with elongated oblong-shaped ray florets. Inflorescences borne on terminals above foliage, arising from leaf axils. Disk and ray florets arranged acropetally on a capitulum. About 8 inflorescences per lateral; about 80 inflorescences per plant.

[0027]Flowering response.—Under natural season conditions, plants flower in mid-September in the Northern Hemisphere and continue to flower for at least three weeks depending on weather conditions.

[0028]Inflorescence bud (before showing color).—Height: About 5 mm. Diameter: About 7 mm. Phyllary color: 143A. Inflorescence size: Diameter: About 3.7 cm. Depth (height): About 1.6 cm. Disc diameter: No disc florets. Receptacle diameter: About 5 mm.
